SPRAYING DEVICE.

SPECIFICATION formingpart of Letters Patent No. 730,316, dated June 9, 1903.

Application lecl Dctoher'ZQ, 1902. Serial No. 129,249, (No model.)

To all wtmn t 'may concern;

Be it known that I, JAMES C. TENNENT, of

Caledonia, in the county of Livingstom'Stat-e of New York, have invented certain new and useful Improvements in Spraying Devices; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forminga part of this specification, and to the reference-numerals marked thereon.y

My present invention relates to spraying devices, and particularly to the class of hand sprayers or atomizers embodying generally a receptacle, an air-pump, and suction or atomizingtubes coperating therewith; and my invention has for its object to provide a machine With which a large volume of liquid may be sprayed or atomized, and also means for agitating the liquid in the receptacle and means for connecting the latter to the pump.

To these and other ends the invention consists incertain improvements in'construction and combinations of parts, all as will be more fully described and the novel features pointed out in the claims at the end of this specification.

In the drawings, Figure 1 is a perspective view of a spraying device constructed in accordance with my invention, and Fig. 2 is a longitudinal sectional Vview thereof.

Similar reference-numerals in the two figures indicate similar parts.

A spraying device constructed in accordance with my invention embodies a suitable receptacle 1, composed of glass or similar non-corrodible material, provided with the annular neck 2, and the separated ribs or headings 8, extending around or at opposite sides of the receptacle and forming a channel, the use and purpose of which will be presently described. 4: indicates a cover or closure arranged upon the receptacle and provided with a flange or rim surrounding the neck 2, to which is secured a band or cinciure 5, lying in the recess in thereceptacle and servin g to securely attach the parts together. At one sideof the cover is provided an aperture and a screw-cap 6 therefor, which may be removed when it is desired to ll the receptacle. The latter, it will be understood, may be of any desired form or size, although piston-head 13.

in the present instance I have shown it as barrel shaped, and `to protect the bottom thereof I have attached to the band a bottom plate '7.

The pump may be of the usual or any desired construction embodying the cylindrical body 8, closed at its forward end by a head 9 and at its outer end by a block 10, in which is guided the piston-rod 11, provided with a handle 12 and carrying at its inner end the The pump is attached at its forward end to the cover 4, at one side thereof, and itis arranged, preferably, in the plane of the band or cincture 5, to which the pump is further secured by a brace-arm 14, extending between the rear side of the receptacle and the lower Lside of the pump-body, as

shown.

The pump may be secured to the cover, the brace-arm fastened to the pump and band, and the latter, also attached to the cover by soldering or otherwise securely uniting the parte, as will be understood.

The head 9 is provided with a concaved inner side, and at its center is au aperture or discharge-orifice 15, Suction-or atomizing tubes 16 have their lower end s extending into proximity with the bottom of the receptacle, while their upper or discharge ends are arranged iu alinement with the side of the orifice 15. It will be noticed that in Fig. 1 of the drawings the tubes 16 are bent within the receptacle, one toward the forward edge and the other toward therear'edge thereof, so that in case the receptacle is partially emptied of its contents one of said tubes will beimrnersed whether the sprayer is inclined'upwardly or downwardly. Owing to the comparatively small diameter of the orifice I arrange the discharge ends of the atomizing-tubcs in opposition to each other at opposite sides of the orifice, so that the full force of the air emitted therefrom-acts upon the liquid iu each tube.V By employing a plurality of tubes it is not only possible to lift a greater quantity of liquid from the receptacle than can he done with a single tube, but the liquid will be more thoroughly atomized and the spray carried a greater distance.

Devices of this nature are often employed for spraying a liquid containing an insoluble powder which will settle to the bottom of the f provided with an orifice, of suction-tubes receptacle unless the latter is-shaken withl sufficient violen ce to keep its contents stirred. To accomplish this object in a simple manner, I provide a tube 1'7, having its lower end leading to the bottom of the receptacle and connected at its upper end to the forward end of the pump at one side. This tube is of small diameter and adapted to conduct a portion of the air compressed in the pump into the bottom of the receptacle, where it serves to agitate the contents of the latter and also to form a slight pressure therein to assist the liquid to rise in the tubes l5.

A spraying device such as I have shown and described is simple and consists ofa few parts, which may be cheaply manufactured. The construction described also permits a receptacle of glass or similar material to be employed which is not subject to the corrosive eiect of liquids.

I claim as my invention- 1. In a sprayer, the combination with a receptacle and an air-pump having a dischargeorifice, of a plurality of suction-tubes leading from the bottom of the receptacle and atopposite edges thereof and having their discharge ends arranged in proximity to said orifice.

2. In asprayer, the combination with areceptacle and an air-pump having the end leading from the receptacle and having their discharge ends arranged in opposition to each other at opposite sides of the orifice.

3. In a sprayer, the combination with a receptacle and an air-pump having the end provided with an orifice, of a suction-tube leading from the receptacle into proximity with the orifice and an air-tube leading from the forward end of the pump into proximity with the bottom of the receptacle.

4. In a sprayer, the combination with a receptacle, a cover thereforand a band attached to the latter and extending around the bottom and sides of thereceptacle to secure the cover thereon, of a pnmpsecured to the cover, connections between it and the band and an atomizing-tube leading from the receptacle and coperating therewith.

5. In a sprayer, the combination with a receptacle having a channel formed therein, a cover and a band and attached to the cover to permanently secure it thereon, lying in the recess, and surrounding the receptacle, of a pump attached to the cover at its forward end, an atomizing-tube leading from the receptacle and a brace-arm secured to the band and pump.

6. In a sprayer, the combination with a receptacle having a channel formed therein extending longitudinally thereof, a cover and a band surrounding the receptacle, lying in the recess, and attached to the cover, of a pump having an orifice and secured at its forward end to the cover and projecting therefrom in the plane of the band, a brace-arm extending between the pump and band and suctiontubes leading from the receptacle and having their discharge ends arranged in proximity to the orifice. Y

'7. In a sprayer, the combination with a receptacle and a pump having an orifice, of a plurality of suction-tubes having their discharge ends arranged in proximity to said orifice and their lower ends extending into proximity with the bottom of the receptacle and 'adjacent to the edges thereof.
